* Optimize NCHANNELS and MSCCL config for gfx942 80CUs

Set appropriately for different NCCL_MIN_NCHANNELS and MSCCL config,
potentially improving communication perf on the MI300x 80CUs

* Delete tools/msccl-algorithms/allreduce_1step_mccl_8_2_16777216_LL.xml

* Change the factor of gfx94 and update msccl config
